### Moments of inertiaUniversity Of Illinois

When doing dynamics problems with moments of inertia you should not use the formulas you remember for second moment of area instead. You will get the wrong answer Observe that the moment of inertia is proportional to the mass so that doubling the mass of an object will also double its moment of inertia.
